Preference data, such as Likert scale data, are often obtained in questionnaire-based surveys. Clustering respondents based on survey items is useful for discovering latent structures. However, cluster analysis of preference data may be affected by response styles, that is, a respondent's systematic response tendencies irrespective of the item content. For example, some respondents may tend to select ratings at the ends of the scale, which is called an ‘extreme response style’. A cluster of respondents with an extreme response style can be mistakenly identified as a content-based cluster. To address this problem, we propose a novel method of clustering respondents based on their indicated preferences for a set of items while correcting for response-style bias. We first introduce a new framework to detect, and correct for, response styles by generalizing the definition of response styles used in constrained dual scaling. We then simultaneously correct for response styles and perform a cluster analysis based on the corrected preference data. A simulation study shows that the proposed method yields better clustering accuracy than the existing methods do. We apply the method to empirical data from four different countries concerning social values. 相似文献

According to recent studies, people on both the political right and left show prejudice toward groups whose beliefs are in conflict with their own. This prediction applies to both cultural and economic dimensions of political beliefs. In three studies (N = 499) we demonstrate that people on both the cultural and economic right and left show negative attitudes toward groups on the other side of the given spectrum and that underlying this effect is the perception of value violation. In two out of three studies, we manipulated the extremity of target worldviews to further explore the causal chain between political beliefs, the perception of value violation, and prejudice. Our results showed a high degree of symmetry between the political left and right in their attitudes toward groups with dissimilar beliefs. However, although people on both sides of the political spectrum show prejudice toward each other, people on the cultural and economic right seem to be more sensitive to value violations than people on the left. 相似文献

A Cantonese syllable-spotting experiment was conducted to examine whether the Possible-Word Constraint (PWC), proposed by Norris, McQueen, Cutler, and Butterfield (1997), can apply in Cantonese speech segmentation. In the experiment, listeners were asked to spot out the target Cantonese syllable from a series of nonsense sound strings. Results suggested that listeners found it more difficult to spot out the target syllable [kDm1] in the nonsense sound strings that attached with a single consonant [tkDm1] than in the nonsense sound strings that attached either with a vowel [a:kDm1] or a pseudo-syllable [khow1kDm1]. Finally, the current set of results further supported that the PWC appears to be a language-universal mechanism in segmenting continuous speech. 相似文献

In this paper, we further investigate the consistency problem for the qualitative temporal calculus introduced by Pujari et al. [A.K. Pujari, G.V. Kumari, A. Sattar, INDU: An interval and duration network, in: Australian Joint Conference on Artificial Intelligence, 1999, pp. 291–303]. We prove the intractability of the consistency problem for the subset of pre-convex relations, and the tractability of strongly pre-convex relations. Furthermore, we also define another interesting set of relations for which the consistency problem can be decided by the -closure method, a method similar to the usual path-consistency method. Finally, we prove that the -closure method is also complete for the set of atomic relations of implying that the intervals have the same duration. 相似文献

通过3个实验考察了汉字字谜任务中的限制解除和组块分解机制及其原型启发效应。实验1a表明,字谜的常规型语义比字谜型语义更容易激活,实验1b采用“学习-测试”范式,结果表明在学习阶段启动字谜语义比启动常规语义更有利于测试阶段的常规语义限制的解除。因此实验1表明常规语义和字谜语义的通达性差异是限制形成和限制解除的认知机制。实验2表明,涉及镶嵌或者笔画单元分解的紧组块比相应的松组块解答率更低,反应时更长,这表明组块分解是字谜顿悟的机制之一。实验3通过实验3a和实验3b分别揭示了在限制解除和组块分解上原型启发比非原型启发以及无启发有更大的促进作用。总之,本研究揭示,汉字字谜任务中存在限制解除和组块分解机制并且原型启发可以促进二者的发生。 相似文献

' We report two studies on the effect of implicitly versus explicitly conveying affirmation and denial problems about conditionals. Recently Evans and Handley (1999) and Schroyens et al. (1999b, 2000b) showed that implicit referencing elicits matching bias: Fewer determinate inferences are made, when the categorical premise (e.g., B) mismatches the conditional's referred clause (e.g., A). Also, the effect of implicit affirmation (B affirms not-A) is larger than the effect of implicit denial (B denies A). Schroyens et al. hypothesised that this interaction is due to uncertainty in the case-wise affirmation of the contrast class of negated elements involved in implicit affirmations. In Experiment 1 we tested this hypothesis by manipulating the set size of the conditional clauses. The results confirm that binary sets, where the contrast class is a singleton, eliminate the differential effect of implicit affirmation and denial. With non-binary sets the interaction is not modulated by the scope of the contrast class (3, 5, 9 elements). Experiment 2 further investigated the role of contrast classes by using class inclusion to construct implicit affirmations (Mammal vs Mammal or Monkey) and implicit denial (No-Mammal vs Mammal or Monkey), in addition to the standard implicit problems mediated by contrast-class inclusion [(No-)Mammal/No-Mammal; Reptile; Snake). Findings indicate that class inclusion (Mammal/Monkey; Reptile/ Snake) only marginally affects performance, and is independent of the type of problem. This would suggest that the implicitness problem-type interaction is dependent on constructing contrast classes. However, the experiment failed to replicate the interaction, even on the subset of problems repeating the abstract letter/number format of Experiment 1. Moreover, with the natural binary set-sizes (vowels/consonants) the implicitness effect was eliminated entirely. 相似文献

The authors examined the means by which people vary movement parameters to satisfy more than 1 constraint at a time in a repetitive motor task. The authors expected that when participants (N = 12) were simultaneously confronted with spatial and temporal constraints in an ellipse-drawing task, they would either exploit the intrinsic amplitude-frequency relationships or activate less natural control regimes to prioritize their movement goals. By focusing on local amplitude and frequency errors and parameter changes from 1 movement to the next, the authors distinguished parameter changes that reflected exploitation of biomechanics from those that required deliberate control. The findings demonstrated that at low movement speeds, participants can pursue multiple movement goals simultaneously; at higher speeds, their capacity to satisfy multiple task goals is reduced. The authors used a new method of inferring deliberate control from movement kinematics in the present study. 相似文献

This paper aimed at investigating the effects of work‐related norm violations (i.e., violations of interpersonal and work regulation norms) and individuals' general beliefs about the world (i.e., social axioms: reward for application, social cynicism) on feelings of shame and guilt in Turkey and in the Netherlands. An experimental study involving 103 Turkish and 111 Dutch participants showed that work norm violations elicited feelings of guilt and shame differently in Turkey and the Netherlands. Specifically, interpersonal norm violation in Turkey elicited feelings of shame and guilt more strongly than did violation of a work regulation norm, whereas no differential effects were found in the Netherlands. As expected, violation of a work regulation norm elicited feelings of shame and guilt more strongly in the Netherlands than in Turkey, whereas violation of an interpersonal norm elicited feelings of shame and guilt more strongly in Turkey than in the Netherlands. The findings provide further evidence for the moderating effects of social axioms: in both countries, participants high in social cynicism felt less ashamed when they violated a work regulation norm than did those low in social cynicism. Our findings are relevant for understanding the underlying mechanisms of norm violations at work, thereby offering a new avenue for investigating cultural differences in the workplace. The latter may be of particular relevance in times of globalization and diversity in the workplace. 相似文献
